Embodiment 1

[0033] An antibacterial and enhanced HDPE pipeline function masterbatch, which is composed of the following components by mass percentage: HDPE resin (model: GM-5010H) 89.94%, four-needle zinc oxide whisker 3%, inorganic nano antibacterial agent 6% (of which nano Copper oxide 3%, nano zirconia 3%), water-based dispersant (dispersant WF211) 0.03%, water-based coupling agent (silane coupling agent KH-560) 0.03%.

[0034] Among them, the melt index of HDPE (model: GM-5010H) is 0.5g / 10min. The melt index test standard is ASTM D 1238.

Embodiment 2

[0036] Except HDPE resin (model: GM-5010H) 86.94%, four-needle zinc oxide whisker 4%, inorganic nano-antibacterial agent 8% (including nano-copper oxide 4%, nano-zirconia 4%), others are the same as in Example 1 same.

Embodiment 1 and 2

[0037] The preparation method of embodiment 1 and 2 is:

[0038] (1) Add deionized water, micron zirconia and water-based dispersant (dispersant WF211) into a vertical grinder in proportion to grind for 90 minutes, and grind it into a nano-zirconia material with an average particle size of less than 200nm;

[0039] (2) Then add micron copper oxide into the vertical grinder and continue to grind the nano-zirconia material obtained in step (1) for 90 minutes, so that the above two raw materials are ground into nano-materials with an average particle size of less than 100nm;

[0040] (3) Then add the water-based coupling agent (silane coupling agent KH-560) into the vertical grinder and continue grinding for 20 minutes to form a water-based nanocomposite antibacterial liquid;

[0041] (4) Ultrasonicate the water-based nano-composite antibacterial liquid obtained in step (3) for 5 minutes and spray it on the HDPE resin (model: GM-5010H) preheated to 90°C on the high-speed mixer wi...

Abstract

The invention relates to antibacterial reinforced HDPE (high-density polyethylene) pipeline functional master batch and a method for preparing the same. The antibacterial reinforced HDPE pipeline functional master batch comprises HDPE resin, tetrapod-shaped zinc oxide whiskers, inorganic nanometer antibacterial agents, water-based dispersing agents and water-based coupling agents. The antibacterial reinforced HDPE pipeline functional master batch and the method have the advantages that the problem of difficulty in dispersing nanometer materials and the problem of particle aggregation can be effectively solved by the aid of a special process for preparing the inorganic nanometer antibacterial agents and a special nanometer dispersing process, accordingly, the tetrapod-shaped zinc oxide whiskers and the inorganic nanometer antibacterial agents can be uniformly dispersed in the antibacterial reinforced HDPE pipeline functional master batch, the antibacterial reinforced HDPE pipeline functional master batch is excellent in antibacterial performance, and the tensile yield strength and the notch impact strength of the antibacterial reinforced HDPE pipeline functional master batch can be obviously improved; perfect effects can be realized by the antibacterial performance, the compressive strength and the ring stiffness of products if 5-15% of the antibacterial reinforced HDPE pipeline functional master batch is added into the HDPE pipeline products.

Description

technical field [0001] The invention relates to an antibacterial and enhanced HDPE pipeline function masterbatch, and also relates to a preparation method thereof. Background technique [0002] In the water supply and drainage piping system, plastic pipes have gradually replaced traditional pipes such as cast iron pipes and galvanized steel pipes and become the mainstream pipes. Compared with traditional pipes, plastic pipes have significant advantages such as light weight, corrosion resistance, small water flow resistance, energy saving, easy and fast installation, and low cost, and are favored by the pipeline engineering industry. HDPE pipe is the replacement product of traditional steel pipe and PVC drinking water pipe. [0003] At present, ordinary HDPE pipes generally have the problems of no antibacterial and antifungal functions, low pressure resistance, and low ring stiffness, and there is no enhancement of nanomaterials and whisker materials.
